Why You’ll Love This Million Dollar Roast Beef Tenderloin

Let’s get right to the good stuff—why this recipe earns its million-dollar name:

  • Minimal ingredients, maximum flavor
  • Tender, buttery beef every single time
  • Looks fancy, cooks easy (my favorite combo)
  • Perfect for holidays, celebrations, or “just because” Sundays

This dish proves that you don’t need a complicated marinade or a long list of spices. When you start with a beautiful beef tenderloin and treat it right, it does all the heavy lifting for you.

Ingredients You’ll Need

For the Beef Tenderloin

  • 1 tsp salt
  • ½ tsp black pepper
  • 2 tbsp avocado oil
  • 4 to 5 lb beef tenderloin, room temperature

For the Herb Butter

  • 4 tbsp salted butter (Kerrygold is my personal favorite for richness)
  • 2 tsp minced garlic
  • 1 tsp prepared horseradish or Dijon mustard
  • 1 tsp minced rosemary or thyme (fresh if you can—dried works too)

That’s it. Simple, honest ingredients that come together in a big way.

How to Make Million Dollar Roast Beef Tenderloin

Step 1: Trim, Tie, and Season the Beef

Start by trimming any excess fat or silverskin from your beef tenderloin if your butcher hasn’t already done this. Then cut the tenderloin in half so you have two even pieces—this helps it cook more evenly.

Tuck the thinner end of each piece under itself and tie with butcher’s twine to create a uniform shape. This little step makes a huge difference in how evenly the meat roasts.

Season the entire surface generously with salt and black pepper. If you’re planning ahead (gold star for you ⭐), place the seasoned beef on a rack in the fridge, uncovered, for at least 10 hours or overnight. This dries the surface slightly and helps create a beautiful crust later.

Step 2: Bring the Beef to Room Temperature

If your beef has been chilling in the fridge, take it out and let it rest on the counter for about 2 hours before cooking.

I know it feels strange to leave meat out, but this step helps the beef cook evenly from edge to center. Cold beef + hot oven = uneven results, and we’re not about that life.

Step 3: Sear for Flavor

Preheat your oven to 425°F.

Heat the avocado oil in a large cast-iron skillet over medium-high heat. Once the oil is hot and shimmering, add the tied and seasoned beef tenderloin.

Sear on all sides for about 3 to 5 minutes per side, until you get a deep golden-brown crust. Don’t rush this part—it’s where so much flavor is built. The inside will still be raw, and that’s exactly what you want.

Your kitchen will already smell amazing. This is the moment everyone starts wandering in asking when dinner will be ready.

Step 4: Make and Apply the Herb Butter

While the beef is searing, mix together the softened butter, garlic, horseradish (or Dijon), and rosemary or thyme in a small bowl.

Once the beef is beautifully seared, remove it briefly from the heat and slather that herb butter all over every surface. Be generous. This butter melts into the meat as it roasts, creating incredible flavor and that glossy, restaurant-style finish.

This is where I always think, Yep, this is why it’s called Million Dollar Roast Beef Tenderloin.

Step 5: Roast to Perfection

Insert a probe thermometer into the thickest part of the tenderloin. If your skillet is oven-safe, transfer it directly to the oven. Otherwise, move the beef to a baking dish.

Roast until your desired internal temperature is reached:

  • Medium-rare: about 20–25 minutes (125–130°F before resting)

Once it hits temp, remove the tenderloin from the oven and place it on a cutting board.

Step 6: Rest, Then Slice

This part is non-negotiable. Let the beef rest for 15 to 20 minutes before slicing. Resting allows the juices to redistribute, so every slice stays moist and tender.

After resting, remove the twine and slice into 1-inch thick pieces. Try not to snack on too many slices before serving—though I won’t judge if you do.

Helpful Cooking Tips (Because We’ve All Been There)

  • Use a thermometer. It takes the guesswork out and saves your sanity.
  • Don’t skip the rest time. Cutting too early lets all that precious juice escape.
  • Butter matters. A high-quality butter really shines here—this recipe doesn’t hide it.
  • If your crust looks dark: That’s flavor, not failure. Trust the process.

And if your herb butter looks a little messy going on? Totally fine. It melts and smooths out beautifully in the oven.

FAQs About Million Dollar Roast Beef Tenderloin

Can I prepare this ahead of time?

Yes! You can trim, tie, and season the beef up to a day in advance. Keep it uncovered in the fridge, then bring it to room temperature before cooking.

What if I don’t have avocado oil?

Olive oil works too—just use one with a high smoke point.

How do I store leftovers?

Wrap slices tightly and refrigerate for up to 3 days. Leftover tenderloin is amazing in sandwiches or salads.

Can I use dried herbs instead of fresh?

Absolutely. Use about half the amount since dried herbs are more concentrated.

Ingredients

Scale

For the Beef Tenderloin

  • 45 lb beef tenderloin, trimmed and at room temperature

  • 1 teaspoon salt

  • ½ teaspoon black pepper

  • 2 tablespoons avocado oil

For the Herb Butter

  • 4 tablespoons salted butter, softened

  • 2 teaspoons minced garlic

  • 1 teaspoon prepared horseradish or Dijon mustard

  • 1 teaspoon fresh rosemary or thyme, minced


Instructions

  1. Prep the beef:
    Trim excess fat or silverskin if needed. Cut the tenderloin in half to create two even pieces. Tuck the thin ends underneath and tie with butcher’s twine to form an even shape. Season all sides with salt and black pepper.

  2. Optional overnight step:
    For the best crust, place the seasoned beef uncovered on a rack in the refrigerator for at least 10 hours or overnight.

  3. Bring to room temperature:
    Remove the beef from the fridge and let it rest at room temperature for about 2 hours before cooking.

  4. Sear the tenderloin:
    Preheat the oven to 425°F (220°C). Heat avocado oil in a large cast-iron skillet over medium-high heat. Sear the beef on all sides for 3–5 minutes per side until deeply browned.

  5. Make the herb butter:
    In a small bowl, mix butter, garlic, horseradish or Dijon, and rosemary or thyme until well combined.

  6. Butter and roast:
    Remove the skillet from heat and generously spread the herb butter over the seared beef. Insert a probe thermometer into the thickest part of the meat. Transfer the skillet to the oven and roast for 20–25 minutes, or until the internal temperature reaches 125–130°F for medium-rare.

  7. Rest and slice:
    Transfer the beef to a cutting board and let it rest for 15–20 minutes. Remove twine, slice into 1-inch pieces, and serve.

Notes

Always use a meat thermometer for perfect doneness.

Letting the beef rest is essential for juicy slices.

High-quality butter makes a noticeable difference in flavor.

Serve with roasted potatoes, green beans, or a simple salad for a complete meal.
